New d3d9_hook.cpp (own file like opengl_hook): inline-hooks IDirect3DDevice9::Present (vtable index 17, discovered from a throwaway device; clean prologue so inline is safe, stdcall() on x86) and read-backs the backbuffer with GetRenderTargetData into a D3DPOOL_SYSTEMMEM surface, swizzles BGRA->RGBA, and uploads it into the shared keyed-mutex texture on a hook-owned D3D11 device (a D3D9 surface isn't D3D11-shareable). Both plain D3D9 and D3D9Ex call this same Present, so one read-back path serves both -- the GPU shared-surface fast path the plan sketched for D3D9Ex wasn't worth it. Wired into the video subsystem (install/remove in dllmain); hook links d3d9. mock_game_test decodes DX9 + DX9Ex frames through the hook; 15/15 ctest (incl. the x86 sub-build). Roadmap: DX9 milestone done and removed (remaining renumbered); architecture + lessons updated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
